Aplicaciones

Regioselective chlorination and oxidizing reagentN-Chlorosuccinimide is used as a chlorinating agent, mild oxidant and swimming pool disinfectant. It is used in the microdetermination of hydrazine salts by titrimetry as well as in the detection of arsenic in the +3 oxidative state. It is also employed in the production of rubber additives. Further, it is used as pharmaceutical intermediate and antibiotic drugs intermediate.

Notas

Light sensitive and moisture sensitive. Incompatible with strong oxidizing agents, strong acids, strong bases, amines, ammonia, iron and iron salts.
